An HPD, as completed by the manufacturer of the product, does not identify "safe" chemicals. The HPD Open Standard enables a product company to report on the chemical ingredients of their products (chemicals are referenced in the Standard as "substances,"), including fully disclosing these contents at the substance level, to as low as 100 parts per million (ppm), or as a residual.
The HPD Open Standard also provides for reporting of health hazards that have been identified by authoritative groups, and are associated with substances being reported in the product. In and of itself, this information does not indicate whether the presence - or absence - of a reported hazard would make a chemical safe or unsafe. The HPD Open Standard defines a set of Priority Lists for the reporting of hazards. Lists are primarily selected based upon criteria developed for the GreenScreen® for Safer Chemicals (http://www.cleanproduction.org/Greenscreen.php). For full details on the hazard criteria used in the HPD Open Standard, see Appendix C of the HPD Open Standard version 2.0. This is available by clicking on this link.
Determination of safety requires additional analysis and assessment - generally referred to as "exposure and risk assessment." Risks of chemicals on human health and the environment are assessed by combining chemical-specific hazard data and an estimation of the extent to which human and other organisms are exposed to chemicals. 3rd party, specialist organizations are typically engaged by product companies to perform such assessments, when available. Product companies who have performed such assessments on their products may also report this information on an HPD. If present, it will be found in the "Notes" sections.
